Flush-mount microphones

Flush-mount microphones

Our line of flush-mount sensors combines the high precision and reliability of G.R.A.S. measurement microphones with the need for fitting sensors into very confined spaces and narrow structures, e.g. in acoustic antennas and beams.

With an installation height of less than 10 mm and thin coax wiring, the flush-mount series can be integrated into literally any design without sacrificing aero-dynamic properties.

  • High precision measurement microphones
  • Very low installation height
  • Integrated preamplifier with plug & measure functionality
  • Wide linear frequency range
  • Wide dynamic range
